Sunlight Calculator

• Accurately measures accumulated sunlight in one specific location

Locating plants under the wrong lighting conditions is one of the most common causes of plant failure. This innovative SunCalc® tool accurately measures the amount of accumulated light that falls on any specific location during a 12-hour period. After 12 hours of operation, only one LED light will flash, indicating the available sunlight as full sun, partial sun, partial shade or full shade. 24-hour auto shutoff. 3-volt lithium battery (included).
